Convert execution time to milliseconds: time.time()

Question

How can I convert the execution time to milliseconds. I already multiplied the start and end time to 1000.

I used time.time()

Execution Time

Result: ('Start time: ', 1596465418538.365)

Remove.IntNonIdUniqueIndex

('End time: ', 1596465418538.399)

('Execution time: ', 3.409385681152344e-05)

time.time() basic unit is second. It's enough to multiply the difference between end and start by 1000 to get the milliseconds.

import time

start = time.time()
time.sleep(1)
end = time.time()
d = end - start
print(f'executed in {d} seconds or {d*1000} milliseconds')

executed in 1.003673791885376 seconds or 1003.673791885376 milliseconds

If you are measuring program execution times, it is best to use time.monotonic() or time.monotonic_ns(). These functions are guaranteed never to go backwards even in the event of system clock updates.

The first returns a value in seconds, the second in nanoseconds.
